the driver started the bus and it started moving identify balance and unbalanced force and with reason
Answers
Answer:
if the bus is moving with a constant speed then it will be balanced force like 10 km in 2sec ,20 km in 4sec ,30km in 6sec
but if the bus is moving with a non contact speed then it will be unbalanced force like
10km in 5sec , 26km in 6sec , 31km in 9sec

Explanation:
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: ... a moving object continues to move at the same speed and in the same direction..
An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving. Look at Diagram B, shown below. These forces are unbalanced, so the object moves to the right.
Unbalanced forces can change the motion of an object in two ways. When unbalanced forces act on an object at rest, the object will move. In the two examples mentioned earlier, the net force on the object is greater than zero. Unbalanced forces produced change in motion (acceleration) and the receivers of the forces - the piano and the rope - moved. Unbalanced forces are necessary to cause a nonmoving object to start moving.
Second, when unbalanced forces act on a moving object, the velocity of the object will change. Remember that a change in velocity means a change in speed, direction or both speed and direction. For example, consider a soccer game. The soccer ball is already moving when it is passed from one player to another. When the ball reaches the second player, the player exerts an unbalanced force - a kick - on the ball. After the kick, the ball moves in a new direction and with a new speed.
Examples of Unbalanced Forces
A force can act on an object without causing it to accelerate if other forces cancel the push or pull of the force.
If you and your friend push on a door with the same force in opposite directions, the door does not move. Because you both exert forces of the same size in opposite directions of the door, the two forces cancel each other.
Two or more forces exerted on an object are balanced if their effects cancel each other, and they do not cause a change in the object's motion. If the forces on an object are balanced, the net force is zero. If the forces are unbalanced forces, the effects don't cancel each other. Any time the forces acting on an object are unbalanced, the net force is not zero, and the motion of the object changes.
If you stand on a skateboard and someone gives you a push, then you and your skateboard will start moving. You began to move when the force was applied. An object at rest - like you on your skateboard - remains at rest unless an unbalanced force acts on it and causes it to move.
